WATCH MOVEMENT Filed Feb. 3, 1926 INVENTOR W1 wam/ ATTOR N EYJ Patented Oct. 28, 1930 RALPH WEIN, OF BROOKLYN, NEW YORK,

ASSIGNOR F ONE-HALF TO ALEX WEIN,

OF BROOKLYN, NEW YORK WATCH MOVEMENT Application filed February I have invented an improved watch movement particularly adapted for wrist watches and the like.

Iy invention relates more particularly to means for insuring a clearance for the balance wheel from contact with the watch case.

Heretofore owing to the small size of the movements in wrist watches and their delicate construction difficulty arose from the failure of the person placing the movements in the cases to accurately position the former therein whereby moving parts of the balance wheel came in contact with the case thereby stopping the watch.

Among other objects of my invention is to shield and protect the moving parts indicated from any danger of contacting with adjacent surfaces.

This I accomplish by inserting a guard bar as shown in the annexed drawing which provides a protective guard or shield to effect the correct positioning of the watch, and to complete the regularity of the peripheral contour of the movement.

Having thus generally stated some of the more novel features and objects of my invention, I will more particularly describe the same, reference being made to the accompanying drawings, in which:

Figure l is a plan View of a watch movement shown in broken lines with my invention applied.

Figure 2 is an end view of same.

Figure 3 is a perspective view of a preferred form of my invention.

In the drawings there is disclosed the conventional frame 11 of a Watch movement having the parts 12 and 13 mounted on the body 14 of the frame.

The parts 12 and 13 are recessed to provide shoulders or seats 15 and 16, respectively, to receive the guard bar 17 which may be made of any suitable material and which may be attached thereat in any suitable manner, such as by the screws 18.

The guard bar 17 shown in the drawing is arcuate in contour and is preferably of such thickness that it does not extend or protrude beyond the body 14 or other parts of the frame thus not interfering with the proper and interposed 3, 1926. Serial No. 85,804.

positioning of the movement in the watch case.

I do not limit my invention to the construction illustrated in the drawing as instead of the bar shown, aring may be substituted and be within the purview of my invention which includes any construction suit able as a protective guide to properly position the movement within the watch case, or the bar may form an integral section of the part 12 or 18.

Having thus described my invention and reserving for myself the right to make alterations and changes therein without departing from the spirit and scope of the invention as defined by the appended claims, I claim:

1. In a watch, having a case, a frame, and a balance wheel forming part of the movement, elements mounted on said frame, said elements having shoulders formed so as to provide seats, and a protective shield disposed in juxtaposition to the balance wheel between the case and the balance wheel, said shield having its ends attached to the seats in said elements.

2. In a watch, having a case and a balance wheel forming part of the movement, a frame having shouldered seats, and a protective shield having its ends attached to said frame in said seats, said shield being in juxtaposition to wheel.
